Tests include micron (average diameter), staple length and strength, length-diameter profile and yield.

A popular testing solution for animal owners, fleece testing helps you to improve quality. We test greasy wool samples using a variety of low-cost methods that are specifically designed for animal selection purposes.

How to understand your test results

Yield Determining the amount of clean wool (wool base), and vegetable matter contamination in a sample
Mean fiber diameter The average fineness of the wool (fiber thickness), which is a primary determinant of wool value
Color Measured as tristimulus values, and normally used to assess clean color brightness (Y value) and yellowness (Y-Z value)
Staple length and strength We use the average staple length, staple strength and position of break to assess the performance of apparel wools in the worsted processing system
Bulk This measures the fibers’ ability to fill space and also relates to resilience, which are important properties for applications such as carpets, futons, and insulation
Fiber curvature Relates to bulk, compressibility, and crimp and is cited as an influence on processing
Fiber diameter distribution Information about aspects of the diameter distribution may affect assessments of comfort and processing performance
Medullation Refers to the hollow fibers in wool and other animal fibers, which causes uneven dye uptake and adversely affects appearance in apparel wools (but may be desirable for some carpet types)
Conditioned mass Wool absorbs up to 20 percent of its weight as moisture, so invoicing is based on an agreed moisture content or regain (known as the conditioned mass)
Length After Carding (LAC) A standardized method of simulating semi-worsted processing to estimate mean fiber length after processing. Results Are expressed in Hauteur, Barbe, and length distribution statistics
